Definitions

  • old stitches may slide off into this-slot after knockover, to reduce wear and stress on the threads.
  • the throats thereof are defined as a U-shaped opening, the termination of the .U serving as the effective stop for movement of the stitches during the knitting cycle.
  • This prior art configuration leads to certain consequences.
  • the thread ends which run between the wales even after knock-over are greatly affected during the upward movement of the needles by contact with the terminal step of the said opening.
  • the needle shafts become thicker toward the base ends thereof, the space between the shafts and the sinker plates is comparatively small, so that only thread material of rather narrow guage can be worked without interference.
  • the affect upon the threads running between the wales at the throat terminal end of the aforementioned sinkers may be lessened to a certain extent by moving the sinkers slightly backward during the upward thrust of the needles. However, during this additional movement, waste of drive power of the warp knitting machine is increased. It is also known to use sinkers for warp knitting machines which have no terminal throat step, but serve merely to hold down the beginning of the goods. Unfortunately, using machines which are equipped with sinkers of this type, only a comparatively inexact stitch pattern can be produced, since the old stitches are not sufficiently supported at the knockover point.
  • the new stitches are thus free to move sideways in the realm of the lengthened throat, so that the friction on the needle shafts is reduced and at the same time thicker thread material may be utilized.
  • FIG. 1 is a plan view of a sinker in accordance with the present invention having a step-formed angularity formed at'the bottom portion of the throat thereof;
  • FIG. 2 is a plan view of a further sinker in accordance with the present invention, having a nose-formed angu- 1 In the embodiment of the invention seen in FIG. 1,-
  • a protruberence is formed at the lower edge of the sinker throat.
  • the angularity is more specifically defined by step 7. Adjacent to the angularity 6, the throat 4 is extended by a slot 10 extending into the upper part of the throat.
  • the protruberence 6 comprises a nose 8. Beyond such protruberence the throat is again extended by a slot 100.
  • the dotted line 9 illustrates the maximum backward position of a needle (not illustrated), which demonstrates how the threads can expand into the enlarged throat at slots 10 or 10a.
  • a sinker for a warp knitting machine having a protruberence angle in the bottom portion of the throat thereof, said protruberence functioning as a knockover stop during the knitting cycle, and a slot portion formed at said throat beyond said protruberence, for enabling expansion of stitches beyond said protruberence after said knock-over.
